Washington, Oct 31: A new research has determined that ancient meteorites that are among the oldest rocks ever found, still contain magnetic records about the very early history of planets.
MIT planetary scientist Benjamin P. Weiss did the research.
Weiss and his five co-authors examined pieces of three meteorites called angrites, which are among the most ancient rocks known.
The analysis showed that surprisingly, during the formation of the solar system, when dust and rubble in a disk around the sun collided and stuck together to form ever-larger rocks and eventually the planets we know today, even objects much smaller than planets — just
160 kilometers across or so — were large enough to melt almost completely.
